To all whom z't may concern:

Be it known that I, CHARLES E, NUTrING, a citizen of the United States, residing at Hopedale, county of Worcester, State of Massachusetts, have invented an Im rovement in F illing-End Catchers for oms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing[` representing like parts. his invention relates to improvements in automatic filling replenishing looms and its object is to provide a simplified means which can be readily applied to la usual form of loom for catching and retainingthe trailing end of the filling running from an abandoned filling carrier after its discharge from the shuttle by the transferring mecha nism so that the filling end will not be caught and carried by the shuttle orA the freshly inserted filling carrier into the cloth upon the succeeding pick.

This object is accomplished in the present invention by yieldably supporting from desirably the a stationary part of the loom, transferrer stud, a preferably flexible plate having a filling engaging member, which is so positioned that it will approach, and preferably engage, the rear, wall of the aperture inthe lay through which the abanbeats up, then as the lay recedes 'after the filling carrier has been discharged will catch the trailing filling end and pull it from the eye of the shuttle.

,A further object of the invention is to provide an improved means for supporting the filling end catcher in which theresllient means for retaining the catcher in a normal extended position will be wholly inclosed so that its operation will not become im aired by accumulation of lint or other detr1tus.

A further object of the invention is to provide means for adjustably positioning the filling end catcher which will not modify its dust excluding character.

Other objects and features of the invention will more fully appear from the accompanying description and drawings and will be pointed out in the following' claims.

In the drawings:

Figure 1 is a side elevation of a suflicient portion of the battery end of a loom of the well known Northrop type to illustrate the application of the present invention thereto.`

abandoned filling carrler as it is discharged from the shuttle and is not concerned with partly in vertithe particular construction or operation or A the general features of the loom to which it 1s appl1ed. For convenience in illustration a preferred embodiment of my invention is shown. as embodied in an automatic filling replenlshlng loom of the well known Northrop type. In this type of loom the frame or loom slde 1 supports at the transfer end of the leom a' hopper stand 2 upon which is mounted'a rotary hopper 3 which carrles a circular series of fresh filling carrlers 4. The stand 2 has the usual laterally extending transferrer stud 5 upon which the transferrer 6 is pivotally mounted and the transferrer is provided with the usual dog 7 which, upon call for filling replenishment, is elevated into the path of the bunter 8 carried by the lay 9.

rllhe engagement'of the bunter 8 upon the moving lay and the dog 7 of the transferrer oseillates the transferrer to cause its head to thrust a fresh filling carrier from the hopper into the shuttle and drive out the abandoned filling carrier which is until that time retained in the jaws of the shuttle. v

The lay 9 has the usual shuttle box 10 and the shuttle box and lay are provided with a vertical aperture 11 through which the filling carrier is discharged from the shuttle by the transferrer.

A chute 12 which bracket 13 secured to the end of the lay by a suitable bolt 14 serves to direct the abandoned filling carrier 15 into the usual rece tacle.

illing replenishing looms customarily comprise means operable in conjunction with the transferring mechanism for cutting and clamping the filling' leading from the cloth`to the filling carrle'r about to be discharged closely adjacent the eye of the shuttle. When therefore the lllng carrier is discharged from the shuttle it 1s necesis carried by an arm or sary to drawI the severedand trailingvlling endl through the `eye ofthe shuttle and away from the shuttle before the shuttle is sent through the.v shed upon the next p ick 5 succeeding transfer, otherwise the trailing filling end islikely to be dra-wn into the web of cloth where it will produce a defect in the weave. v

' I am aware that various means have b een provided for catching such trailing filling ends and the present invention is intended to provide a simple construction which may be readily' applied to a usual form of loomwithout requiring modification of the loom structure, which will be clust proof and in which the parts are so constructed that they will no t be likely to become broken or loosened during the operation of the loom. e

' In the preferred embodiment of the invention disclosed herein the filling catcher comprises an inte al flexible plate of resilient materialv whic preferabl is of L-shaped form comprising a mem er 16 having a toothed-or serrated upper edge 17 and a member 18"which is s idably mounted in a 'guideway 20. between complementary lsec- .tions 21, -22 of a bracket 23 having at its upper end a boss 24: bored horizontally to receive and lit a supporting rod 25 which the loom frame but preferably is connected .to the lower end of an arm 26 which has at its upper end a boss 27 secured upon the transferrer stud 5 by a set screw 28 or other suitable f means. In such construction the adjustability of the arm 26 about the transferrer stud 5 and the adjustment of the bracket 24 about the stud 25 provides means whereby thje filling end catcher 16 may be adjusted both vertically aiidhorizontally so that the catcher may be positioned in any desirable relation to the lay and the path of the shuttle.

Furthermore the constructionpis such that the bracket 23 may be adjusted `longitudinally of the lay upon the stud 25 so that the filling end catcher may be held in any desired osition.

InV t e operation of the loom the lay does not always stop in exactly the same position upon its beat-up. It is however desirable that the filling end catcher should engage upon every beat-up the rear wall of the aperture in the lay through which the abandoned filling carrier is discharged. Means therefore are provided for yieldably supporting the filling end catcher. Y

In the illustrative embodiment of the inventioii disclosed herein the .`mexiiber,21l of the bracket 23 which supports the 'filling end catcher desirably is in the form of ilat plate while the com lementary mem-f ber 22 of the bracket contains a recess which forms the position.

vstruction the filling end catcher may be may be carried by any stationary portion of These complementary members'may be formed in any suitable manner to provide a suitable support for the illingend catcher v and a closed housing for the spring which retains the filling end catcher` in normal eX- tended position.

The member 22 as illustrated herein desirably is provided with a hollow box-like housing 29 which is closed at both ends and in conjunction `with the member 21 of the bracket forms aclosed chamber for the helical spring 30 which serves to hold the filling end catcher in normal, or extended,

One endV of the spring -30 abuts against vthe inner wall-*31 of the housing while the opposite end 32 of the spring engages an oft'- set end portion 33 of the member 18 of the lling'end catcher. By reason of this constamped orforg'ed from a plate by a very simp e operation and when assembled in the bracket will provide .a construction which is free of joints and the consequent likelihood of loosened parts. Furthermore the construction is such that dust, lint and other foreign materials are entirely excluded from thel chamber in which thel spring is located which maintains the filling end catcher in normal extended position. Thus obstruction to the proper. operation of the lilling end catcher is avoided.

In the operation of the loom filling carriers occasionally are impro erly discharged so that they may be caught between the rear wall of the lay as it moves forward and the construction may be made within the mean- .in and scopefof. the following claims.

aving thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a iilling replenishing loom comprising a lay having an aperture therethrough to permit the discharge of an abandoned illing carrier and having a stand provided with a transferrer stud and a transferrer mounted thereon, a bracket carried by said transferrer stud comprising complementary lmembers-forming a closed housing, a filling 'end' 'catcher comprising a flexible plate 'formed of resilient material having a member-adapted to engage the rear wall of the aperturein the lay as the lay beats up" and a member having an offset end extending into said housing, a spring inclosed in said housing engaging the offset end of said member and acting normally to retain the filling end catcher in projected position but adapted to permit said filling end catcher to yield bodily whereby a smash will be prevented if an obstruction is caught between the filling end catcher and the lay as the latter beats up.

2. In a filling replenishing loom comprising a lay having an aperture therethrough to permit the discharge of an abandoned filling carrier and having a stand provided with a transferrer stud and a transferrer mounted thereon, an arm rotatably adjustable upon and depending from said transferrer stud, a stud extending from the lower end of said arm in parallelism with the lay, a bracket adjustable rotarily and longitudinally on said stud and a filling end catcher mounted in said bracket whereby said filling end catcher may be properly positioned in respect to the lay but adapted to yield if an obstruction is caught between the filling end catcher and the lay as the latter beats up.

3. Filling end catching mechanism for automatic filling replenishlng looms comprising a bracket adapted to be adjustably secured to a stationary part of the loom formed of complementary sections which when assembled provide a closed box-like housing and a guldeway, an integral L-shaped plate of resilient flexible material, one member of which is provided with means for engaging the trailing filling end and the other member of which is slidably mounted in said guideway and provided with an offset end and a spring within said closed housing engaging the oset end of said plate within said housing and acting to maintain the plate in extended position.

In testimony whereof, I have signed my name to this specication.

CHARLES E. NUTTING.
